Abstract :
A l∞ control problem is formulated for digital finite-word-length (FWL) controllers with synchronous sampling and fixed-point arithmetic. The l∞ FWL controllers design problem is reduced to the problem of solving a quadratic matrix inequality (QMI) such that the closed-loop system is asymptotically stable. The approach can be generalized to deal with other problems such as H∞, H2 and LQR FWL control problem
